Apparatus for applying tension to flexible items

ABSTRACT

An apparatus for applying tension to flexible items, including wire, barbed wire, cable, or rope, are described herein. A stationary clamping member is fixedly attached to a first end of a guide bar, extending outwardly therefrom, while a non-stationary clamping member is movably mounted to the guide bar. The first flexible item is secured in the stationary clamping member, while the second flexible item is secured in the non-stationary clamping member. A tensioning assembly, such as a ratchet-like assembly engaging notches in the guide bar, is adapted to move the non-stationary clamping member away from the stationary clamping member, thereby tensioning one or both flexible items. Once the flexible items have been tensioned, they can be connected together while under tension.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a divisional application, claiming priority to the prior-filed, co-pending United States application for patent, having the application Ser. No. 12/384,712, filed Apr. 8, 2009, which is incorporated by reference herein in its entirety.

FIELD

Embodiments usable within the scope of the present disclosure relate, generally, to apparatus usable for applying tension to flexible items, such as wire, barbed wire, cable, rope, or other flexible items. Once the flexible items have been tensioned, they can be connected together while under tension.

BACKGROUND

A common difficulty when tensioning flexible items, most notably barbed wire, is the loss of tension when connecting two lengths of adjacent, tensioned flexible items together. It has long been a difficult problem in the art to bring two pieces of wire in close proximity, with enough overlap between the lines to allow the formation of a tight and secure connection therebetween, without creating slack and losing tension in either side of the lines when forming the connection.

The most common method of attachment between flexible items involves providing a sufficient quantity of slack, non-tensioned line from each flexible item, used to twist together at an attachment point, where a connection between lines is to be formed. The attachment point is normally located at or in close proximity to a device utilized to apply tension to one or both of the lines, with the slack line used to form the connection extending past the tensioning device. The free ends of two flexible items are normally pulled approximately even with one another, and the connection is then formed by twisting or clamping the slack portions of the lines together, or using other similar methods of attachment. The method used to connect the ends of two pieces of line is critical for maintaining tension in each line and preventing subsequent breaks in the lines. The two arrangements generally used to connect adjacent lines are commonly known as a figure eight arrangement, and the “Western Union Wrap.”

A figure eight arrangement is formed by bending the free end of one line to form a loop, while wrapping a portion of the free end that extends past the loop around the opposing end of the line. The free end of the other line is passed through this loop, and then the same procedure is performed with the other line, to form two connecting loops between the lines. This type of connection is disadvantageous, as a crimp is often created in each loop when tension is introduced into the line, which can cause the line to break. While a reduced amount of tension can be introduced into the line to prevent breakage, this is highly undesirable, as insufficient tension along the flexible items can mitigate their effectiveness. However, use of appropriate tension can also lead to the creation of undesired slack in the line, as the introduction of tension can flatten and crimp the loops, which lengthens the line, thereby reducing the overall tension.

The Western Union Wrap is generally regarded as superior to the figure eight arrangement. To form this type of connection, approximately eight inches of two parallel lines are overlapped, and at the midpoint of the overlap, one of the lines is wrapped in a tight helix around the other. The second line is then wrapped in a tight helix around the first, again beginning at the midpoint of the overlap. The two helixes are continued in opposing directions. When tension is introduced to the line, the two helixes pull against each other in opposition, which tightens the helixes and completes the connection. This type of connection generally does not cause crimping and is much less susceptible to breakage or the generation of slack when compared to the figure eight arrangement. However, use of the Western Union Wrap still requires engagement of the non-tensioned, slack ends of each line, which always introduces some amount of slack once the connection is made, as the tension maintained on the remainder of the lines must be distributed over the non-tensioned portions of line used to from the connection.

Existing tensioning apparatuses include devices such as the Durbans Red-D-Rod, and similar devices that are designed to pull flexible items toward one another. This method results in at least some slack being maintained in the lines, since devices of this type are only able to apply tension up to the point where the connection is to be made, without pulling the lines past one another. Then, slack portions of the lines are used to form the connection, as described above, rather than tensioned portions of line. Additionally, once the connection is made and the flexible items are released from the apparatus, the lack of tension immediately adjacent to the connection is transferred and distributed throughout the connected items.

A need exists for apparatus and methods usable to apply tension to flexible items that improve upon existing methods and devices by providing tension at the point of connection between adjacent flexible items, in excess of what is possible using existing devices and methods.

A further need exists for apparatus and methods usable to pull adjacent lines past one another, rather than simply even with one another, to provide additional tension.

A need also exists for apparatus and methods able to compensate for the torque that occurs within lines during the application of tension, thereby enabling tension to be applied in excess of what is normally possible.

Embodiments usable within the scope of the present disclosure meet these needs.

SUMMARY

Embodiments usable within the scope of the present disclosure provide for the connection of flexible items, such as wire, barbed wire, cable, rope, or other similar items, to form a secure engagement therebetween, by utilizing continuous tension, applied to the free ends of either or both of the flexible items, thereby pulling the free ends of the flexible items past one another, until a sufficient overlap between the two lines exists to complete a connecting wrap between the lines. As such, embodied apparatus and methods can be usable to control the amount of tension provided to one or more lines, to control the direction of the lines relative to one another, and to control the torque created on the flexible items due to their respective directions relative to one another and the tension applied, by positioning the tensioned lines in an orientation that permits a connecting wrap to be formed under tension.

Tension can be provided to the flexible items by axially extending the free end of one line, or of two lines sequentially or simultaneously, while maintaining the other end of the lines in a fixed position. The lines can be extended past one another until sufficient overlap exists between the lines to form a connection. Once the two lines are sufficiently extended, a rotational wrapping motion between the lines can be used to provide additional tension. To move the free ends of one or both flexible items away from each other, a tensioning assembly can be used. The tensioning assembly can include a ratchet device, though in other embodiments, a pulley, lever, or similar device could be used to move the free end of one or both lines. When two lines are to be connected to one another, the connection can be made while the two lines are under tension by rotating the lines about each other. Forming a connection in this manner further increases the tension on each line compared to conventional connection methods that utilize slack portions of adjacent lines to form connecting wraps.

In an embodiment, two flexible objects, which are intended to be connected to one another, can be retained using clamping members attached to either end of a guide bar. One of the clamping members can be stationary, being fixedly mounted to an end of the guide bar, while the other clamping member is non-stationary, being designed to move laterally along the guide bar, away from the stationary clamping member. The non-stationary clamping member can thereby be used to pull the free end of one flexible item past the stationary clamping member, to which the other flexible item is affixed, thereby pulling the ends of each line past one another, and in opposite directions from each other. This movement produces tension in both flexible items extending from the clamping members to the first fixed point of each line, in excess of what is normally provided through conventional tensioning devices, forming an overlapping portion between the lines sufficient to connect the lines together.

Normally, the introduction of tension to the flexible items causes torque, resulting from the pull from each line at each connection point. If the torque is not controlled, the force can cause the apparatus to flip, thereby reversing the position of the clamping members and creating slack in the lines. To alleviate this potential difficulty, an embodiment can include line guides affixed to one or more of the clamping members, e.g., extending perpendicular to and outward from the clamping members. The line retained by the stationary clamping member can pass through the guide attached to the non-stationary clamping member, while the line retained by the non-stationary clamping member can pass through the guide attached to the stationary clamping member. Two line guides can work in opposition to apply equal and opposite forces to counter the torque on the lines, while in turn canceling the force applied by the other line guide. The torque moment on the lines is thereby cancelled, and the creation of additional slack on the lines is thereby avoided.

The design of the embodiments described above can thereby place two flexible objects in an optimal plane, and separated by an optimal distance, for forming a connection using a Western Union Wrap or other similar method of engagement. The flexible objects can also be provided with additional twisting to complete the connection. Forming the connection between overlapping portions of the lines extending between the two clamping members of the apparatus can enable tension to be maintained up to the point where connection is made. The accompanying twisting used to complete the connection can shorten both lines and increase the tension therein, thereby eliminating any loss of tension that occurs when the clamping members are released.

In an embodiment, a locking, ratchet-type assembly can be used to move the non-stationary clamping member away from the stationary clamping member, to pull one of the lines past the other to form an overlap. The guide bar can include a plurality of notches formed in a side, angled away from the stationary clamping member. A ratchet tongue engaged with the non-stationary clamping member can be used to engage and disengage selected notches. The assembly can further include a ratchet safety that engages with the notches to push the guide bar and, correspondingly, the non-stationary clamping member away from the stationary clamping member, thereby preventing a loss of tension in either flexible item during movement of the non-stationary clamping member. A tensioning member, such as a spring, can engage the ratchet tongue, to maintain the ratchet tongue in constant engagement with the plurality of notches, except when intentionally disengaged.

In use, the apparatus can pull one of the two free ends of a clamped flexible item past the free end of another, then in an opposing direction relative to the other line, by moving the non-stationary clamping member away from the stationary clamping member. Use of a locking, ratchet type system prevents slippage and reduction in tension of the lines after each advancement of the ratchet tongue is made. Once the two lines are pulled past one another and positioned such that they overlap each other, they can be wrapped together by inserting a lever therebetween and rotating the lever, thereby twisting the lines about each other and providing additional tension to the connection. The force required to rotate the lever is inversely proportional to the length the lever extends beyond the plane in which both of the flexible items are located. The length of the lever is restricted by the distance between the lines to be connected and the tensioning mechanism and/or any adjacent lines above or below the lines being connected.

In an embodiment, the lever used to twist the lines together can include a tapered sleeve inserted between the two flexible items to create a pivot point. The tapered sleeve can have the same internal diameter throughout its length, and an outer diameter that tapers in one direction from one end to the other end. This taper allows the sleeve to be removed from between the two flexible items after they have been wrapped with less difficulty than would otherwise be incurred. A lever, such as a solid bar six inches in length, having a diameter less than the inner diameter of the sleeve, can be inserted into the sleeve and rotated to wrap the lines. A second bar of equal size can be inserted into the opposite end of the sleeve and used when the rotational travel of the first bar is terminated by contact with the guide bar that extends between the two clamping mechanisms used to retain the lines. Use of two bars to twist the lines together allows less force to be used to form the connection, and enables a greater amount of twisting to be provided to the lines, thereby removing as much slack as possible.

In an embodiment, the stationary clamping member can be removable from one end of the guide bar and positioned at the opposite end. The non-stationary clamping member can then be inverted, and the apparatus can be used to pull a line from one clamping member toward the other, which can be secured to a point on the line beyond that where a connection is to be formed. A hook can be formed on an end of the guide bar to enable the apparatus to be readily attached to a fixed point, so that a free end of a single line can be drawn toward that point, in lieu of or in addition to using a second line secured in the stationary clamping member.

Embodiments usable within the scope of the present disclosure thereby enable connections to be formed between flexible items while virtually eliminating slack in the lines, providing an exceptional advantage over existing devices and methods for connecting flexible items to one another, e.g., by pulling the free end of one line past that of another line, to apply tension in excess of what is normally possible, forming a tensioned overlap between adjacent lines usable to form a connecting wrap therebetween. Concurrently, line guides can be used to apply equal and opposite forces to the lines to prevent the resulting torque caused by the application of tension from inverting the apparatus and creating slack in the lines. By moving the ends of the lines past one another and compensating for the torque inherent in the tensioning process, embodiments described herein can exceed the tensioning ability of conventional tensioning apparatus.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Before explaining the present invention in detail, it is to be understood that the present invention is not limited to the particular embodiments described and depicted and that the present invention can be practiced or carried out in various ways.

As described previously, the two generally accepted types of connections used to attach wire, barbed wire, cable, rope, or other flexible items, include the Western Union Wrap and the figure eight arrangement. FIG. 1B depicts the figure eight arrangement, which is formed by bending a free end (10) of a first line (11) to form a first loop (12), while retaining a sufficient length of the first line (11) extending past the first loop (12) to form a number of wraps (14) around the fixed end (16) of the first line (11). The same procedure is then utilized after the free end of a second line (17) has been passed through the first loop (12). The second line (17) is used to form a second loop (18), which interlocks with the first loop (12), then additional wraps (14) are provided around the anchored end (19) of the second line (17). The fixed and/or anchored ends (16, 19) of the lines (11, 17) can be attached at a number of locations, including a post, anchor, or other lines. As described previously, this type of connection can create crimps in the loops (12, 18) as tension is introduced into the lines (11, 17), which can result in breakage of either line should the applied tension exceed the tolerance at any specific point along the connection.

FIG. 1A depicts a Western Union Wrap, which is generally regarded as a superior connection to the figure eight arrangement. The Western Union Wrap is formed by overlapping a first line (20) and a second line (22). Beginning at the midpoint (24) of the overlap, the free end (21) of the first line (20) is wrapped around the anchored end of the second line (22), and the free end (21) of the second line (22) is wrapped around the anchored end of the first line (20). A number of wraps (25) are thereby formed, which should be sufficient in number to support the amount of tension to be introduced into the lines (20, 22). When tension is introduced into the lines (20, 22), the wraps (25) pull against each other in opposition, thereby tightening to complete the connection.

Referring now to FIGS. 2 and 3, an embodiment of an apparatus, usable within the scope of the present disclosure, is depicted. FIG. 2 depicts the apparatus at rest, while FIG. 3 depicts the apparatus in operation, engaged with two lines of barbed wire.

The apparatus is shown having a guide bar (30), which extends between a stationary clamping member (32) and a non-stationary clamping member (34). The stationary clamping member (32) (e.g. static or fixed clamping member) is fixedly secured to an end (36) of the guide bar (30). The non-stationary clamping member (34) (e.g. movable clamping member) can be moved along the guide bar (30) using a ratchet mechanism, which is shown including a ratchet lever (50), usable to engage and disengage a ratchet finger (60) (e.g., latch) from a plurality of notches (38) formed within one side of the guide bar (30). The notches (38) are shown formed on the side of the guide bar (30) opposite the side from which the stationary clamping member (32) extends, and can be angled away from the stationary clamping member (32).

FIG. 4 depicts an embodiment of the stationary clamping member (32), which is shown fixedly attached to the guide bar (30) at a first point (40) and a second point (42). While FIG. 4 depicts the stationary clamping member (32) attached at two attachment points (40, 42) using rivets or similar members, other connection methods, such as welding, nuts and bolts, or other suitable means for anchoring the stationary clamping member (32) to the guide bar (30) can be used, at any number of attachment points. The stationary clamping member (32) is shown having a bottom mounting plate (44) and a top mounting plate (46), which are each connected to the guide bar (30) at the attachment points (40, 42). The top mounting plate (46) extends longitudinally toward the end (36) of the guide bar (30) and perpendicularly upward from the guide bar (30) to provide a pivot connection point (48) at which a clamping lever (50) is engaged.

A spring anchor (52) is shown extending perpendicularly outward from a side of the guide bar (30) and the top mounting plate (46). The spring anchor (52) has an aperture (52) therethrough, which enables a hook (56) of a spring (55) to be engaged. A second spring anchor (68) with an aperture (70) therethrough, extends from the clamping lever (50) to engage a second hook (57) of the spring (55). The spring (55) is utilized to maintain pressure on the clamping lever (50), which maintains a first clamping plate (62) and a second clamping plate (64) in abutment. The clamping plates (62, 64) maintain a flexible item therebetween when in abutment. The clamping lever (50) is fixedly attached to a clamping piece (66) of the stationary clamping member (32), proximate to the second clamping plate (64) at an attachment point (67). By maintaining the clamping lever (50) under tension, the spring (55) maintains the first clamping face (62) (e.g., first clamping surface) in abutment with the second clamping face (64) (e.g., second clamping surface). The second clamping face (64) is shown secured to the bottom mounting plate (44) at a first connection point (45) and a second connection point (47), which can include use of welds, rivets, nuts, bolts, or similar suitable items.

A safety lip (71) is depicted extending over the point of abutment for the clamping faces (62, 64), integrally attached to the second clamping face (64) and support body (65). The safety lip (71) protects a user of the device and facilitates retention of a flexible item between the clamping faces (62, 64). FIG. 4 also depicts a line guide (72), having one or more guide arms (74), attached to the bottom mounting plate (44) at the connection points (45, 47). The line guide (72) extends perpendicularly outward from the bottom mounting plate (44) on the same side as the spring (55) and clamping lever (50). The guide arm (74) provides a bounded area (depicted in FIG. 2 at 76) within which flexible items can be placed, the guide arm (74) countering the torque produced in the flexible item concurrent with the application of tension.

FIG. 5 depicts an embodiment of the non-stationary clamping member (34), which is operably moved along the guide bar (30) using a ratchet lever (51). The ratchet lever (51) is shown formed from two steel plates, which are engaged together at engagement points (82) to form a handle (80). The main body of the non-stationary clamping member (34) is shown having a top mounting plate (84) and a bottom mounting plate (86), which are fixedly attached together at an attachment point (88), such a by use of welding, rivets, or other suitable means of attachment. The ratchet lever (51) is shown attached to both mounting plates (84, 86) using a rivet (92), bolt, screw, or similar object to extend through the lever (51) and both mounting plates (84, 86), at a pivotable connection point (90). The connection between the lever (51) and mounting plates (84, 86) enables the lever (51) to rotate and pivot about the connection point (90).

The rivet (92) or other object used to secure the connection point (90) is usable as a ratchet tongue, which sits within notches (38) in the guide bar (30). To move the non-stationary clamping member (34) along the guide bar (30), the ratchet lever (51) can be pivoted about the connection point (90), which pulls a ratchet safety mechanism (60), pivotably mounted between the steel plates of the lever (51), extending into the top and bottom mounting plates (84, 86). The ratchet safety mechanism (60) is depicted in greater detail in FIG. 6. The ratchet safety mechanism (60) is shown having a tongue (94), which is retained in engagement with the notches (38) of the guide bar due to tension provided by a ratchet spring (96). The ratchet spring (96) is shown anchored to the ratchet safety mechanism (60) at a first end (98) and through a spring anchor (100) in the top mounting plate (84) at a second end (97). Pivoting of the ratchet lever (51) thereby pulls the ratchet safety mechanism (60), enabling disengagement of the tongue (94) from a first notch and subsequent engagement with a different notch, while simultaneously enabling disengagement of the ratchet tongue (92) from its respective notch and subsequent engagement with a notch farther along the guide bar (30).

The first end (101) of a clamping spring (102) is also engaged with the spring anchor (100) on the top mounting plate (84). The second end (103) of the clamping spring (102) is engaged with a second spring anchor (106) disposed on a clamping lever (104). The clamping lever (104) is pivotably mounted outside of the top mounting plate (84) at a pivot point (110). A clamping arm (112) of the non-stationary clamping member (34) is attached to the clamping lever (104) at the pivot point (110) and at a connection point (122). A first clamping face (114) (e.g., first clamping surface) is formed at the end of the clamping arm (112), which abuts against a second clamping face (116) (e.g., second clamping surface), secured to the bottom mounting plate (86) at two connecting points (120). When in abutment, the clamping faces (114, 116) retain a flexible item to which tension is to be applied. The clamping spring (102) retains the clamping faces (114, 116) in abutment by applying constant tension to the clamping lever (104), while the clamping lever (104) can be manually pivoted to enable engagement of a flexible item between the clamping faces (114, 116). A safety lip (121) is depicted extending over the point of abutment for the clamping faces (114, 116), integrally attached to the second clamping face (116) and support body (118).

A line guide (124, depicted in FIGS. 2 and 3), is shown extending perpendicularly from the bottom mounting plate (86), in the opposite direction from the line guide (72, depicted in FIGS. 2-4) extending from the stationary clamping member (32, depicted in FIGS. 2-4). The line guide (124) includes one or more guide arms (126), which form a bounded area (128) within which a flexible item is extended. The line guide (124) counters the torque produced when the flexible item is tensioned. The force of each line guide (72, 124) exerted to counter the torque from the lines is cancelled by that exerted by that exerted by the opposing line guide.

An embodiment of the present apparatus is depicted in operation in FIG. 3. The loose end of a first piece of barbed wire that is to be connected with a second piece of barbed wire is shown extending between the guide arms (74) of the line guide (72) attached to the stationary clamping member. The loose end of the first piece of barbed wire is then clamped between the clamping faces of the non-stationary clamping member. In an embodiment, the clamping faces can be knurled. In a further embodiment, the clamping faces can be curved away from the outer point of the corresponding ends of the guide bar (30).

The free end of the second piece of barbed wire is shown extending between the guide arms (126) of the line guide (124) attached to the non-stationary clamping member. The second piece of bared wire is then clamped between the clamping faces of the stationary clamping mechanism.

Once each piece of barbed wire is engaged between the clamping faces of one of the clamping mechanisms, the ratchet lever (51), which is shown engaged with the non-stationary clamping member using two steel plates (51A, 51B) that each engage one side of the non-stationary clamping member, can be moved back and forth in opposite directions, thereby engaging the ratchet tongue into notches (38) along the guide bar (30). During operation, this movement of the ratchet lever (51) moves the entire non-stationary clamping member along the guide bar (30), thereby pulling the engaged line past the free end of the line engaged with the stationary clamping member and applying tension to both lines of barbed wire.

Once the proper tension has been applied to the lines, a lever can be used to form the connection between the two flexible items. FIG. 7 depicts an embodiment of a lever usable for this purpose. The embodied lever is shown having a tapered sleeve (130) having a cylindrical internal aperture (136) extending completely therethrough, and a tapered outer diameter. The taper of the sleeve (130) facilitates removal of the sleeve from between two lines after forming a connection. A first bar (132) having a first tapered end (138), and a second bar (134) having a second tapered end (140) are inserted into opposing sides of the cylindrical aperture (136) of the sleeve (130). The tapered ends (138, 140) of the bars (132, 134) facilitate a snug fit within the aperture (136).

Once the sleeve (130) has been inserted between lines to be connected and the bars (132, 134) have been inserted into the sleeve (130), the sleeve (130) can be twisted using the bars (132, 134), which forms a Western Union Wrap between the lines being connected. The bars (132, 134) are removable from the sleeve (130) during operation, because when rotated, the bars (132, 134) will contact the guide bar of the apparatus and will need to be removed to allow the twisting of the connection to continue.

FIG. 3 also depicts a hook (142) integrally formed within the guide bar (30) at the end closest to the non-stationary clamping member. The hook (142) enables the apparatus to be engaged with an anchor, while a single flexible item can be tensioned to a fixed object by pulling the flexible item away from the hook (142) using the non-stationary clamping member.

The embodiments described above thereby provide apparatus and methods for applying tension to flexible items and making connections between the flexible items, in a manner that minimizes loss of tension and introduction of slack during formation of the connections.
